Conveyor includes a pipe belt conveyor, lifting conveyor, FU chain conveyor, screw conveyor, vibration conveyor, plate chain bucket elevator.

(A) the type of bulk material handling equipment performance

1, round pipe conveyor type and characteristics. Conveyor belt conveyor can be divided into flat and slot type according to its cross-section type, and later developed type can be called a special type of pipe conveyor belt, such as zipper belt conveyor, belt-type Conveyor belt, belt conveyor, bending belt conveyor, pipe belt conveyor.

Tube conveyor belt can do the horizontal transport, can also be a certain tilt angle up or down transport.

According to their different ways of installation in the field, round pipe conveyor belt can be divided into two kinds of mobile and fixed. Mobile tube conveyor belt equipped with mobile adjustable height device, you can always change the working position and transport height. The supporting device and the base of the fixed type pipe belt conveyor are fixedly installed on the foundation.

Conveyor belt conveyor belt is mainly composed of conveyor belt, support devices, drive devices, tensioning device, feeding and discharge devices and other components.

Various types of pipe belt conveyor drive devices include motors, reducer, drive roller, control devices and safety devices.

Tensioning device is by moving the roller tension to maintain a certain tension, and the belt and roller to produce the necessary friction between the device. The tensioner also loosens the conveyor belt for maintenance purposes. Commonly used tensioning device with manual operation and automatic tension two. Hand-operated device has a screw tension device and winch tensioning device; automatic tensioning device has vertical tensioning device and car-type tension device two.

Belt conveyor structure is simple, operation, installation, maintenance is very convenient, save energy, safe and reliable operation. If designed properly, well maintained, its long service life. Belt conveyor economy is good, within a specified distance, the cost per ton of material transport than other types of transport equipment low.

2, to enhance the type of pipe conveyor belt and characteristics. Most standard conveyors are limited in their ability to lift bulk solids greater than 20 °. Especially in a relatively short horizontal distance, elevated to a higher position, usually using lifting conveyors, including bucket elevator, bucket conveyor, bucket conveyor and bucket elevator several types.

Bucket elevator is the role of the limited space in the material from a low vertical transport to the height, the required small footprint is its significant advantages. Bucket elevator shortcomings is the maintenance, repair is not easy, often need to stop maintenance. Bucket elevator for conveying uniform, dry, fine granular solid material.

Bucket conveyor is particularly suitable for conveying containing block, no grinding of the material.

Transfer bucket conveyor can be used to transport high-strength materials or abrasive nature of the material.

The hoisting bucket conveyer mixes the material the segregation is very small. Bucket elevator for most of the intermittent lifting operations, cast iron, coke, bulk materials, etc. can be very good transport.

3, chain conveyor type and characteristics.

Due to the different attachment of the chain, chain conveyor can be divided into the scale conveyor, scraper conveyor and buried scraper conveyor.

Scale conveyor conveyor capacity, low operating costs, often used to complete a large number of heavy and bulk material with a grinding of the transport of materials.

Scraper conveyor used to transport granular and massive, fluidity, non-abrasive, non-corrosive or medium corrosive materials.

The main advantage of the buried scraper conveyor is the fully enclosed enclosure, where the transported material moves within the enclosure and does not pollute the environment. But also conveying the need to purge the toxic or explosive materials and dust collected by the filter and so on.

4, screw conveyor type and characteristics. Screw conveyors can be widely used for conveying, lifting and loading and unloading of bulk solid materials.

Screw conveyor design is simple, low cost. Screw conveyor conveyor block, fibrous or viscous materials, the solid material is transported there is a tendency to crush. Screw conveyor conveyor length by the transmission shaft and coupling shaft allowable torque limit.

5, vibration conveyor type and characteristics. Vibratory conveyors can deliver abrasive, chemically corrosive or toxic bulk solids, and even high temperature materials. Vibration conveyor can be dust, there is air tight or in the case of pressure delivery materials. Vibration conveyor is simple, easy to operate, safe and reliable. Vibration conveyor and other continuous conveyor, the initial price is higher, while the lower maintenance costs. Vibrating conveyors need low power to transport materials, so the running cost is low, but the conveying capacity is limited, and can not transport the materials with strong viscidity, easily damaged materials and gas-containing materials. At the same time, they can not transport materials at large angles.

(B) installation and construction methods 1, the rack installation.

(2) the horizontal centerline of the drum should be coincident with the longitudinal center line of the conveyor, the deviation should not be greater than 2mm; (2) the roller centerline should be consistent with the longitudinal centerline of the conveyor, the deviation should not be greater than 2mm; Roller axis and the longitudinal centerline of the vertical deviation of the conveyor should not be greater than 2/1000; roller horizontal deviation of the horizontal degree should not be greater than 1 / 1000. 2, the belt bonding method.

(1) cold connection method.

(2) thermal connection method. The role of heat access tool is on the one hand the use of steam heating, on the other hand can be used for pressing tools. When the belt will be hot junction with the tool clamping the mouth, the belt will be heated through the curing reaction, so that raw rubber into vulcanized rubber, the strength of the conveyor belt can reach 85% to 90% of the body strength.
